虽然行为和实验研究已经表明受害和反社会行为之间的联系，解释这种联系的神经相关性相对未知。在目前的研究中，我们从一项纵向研究中招募了青春期女孩，该研究跟踪了从二年级到八年级每年一次的同龄人受害经历报告。根据这些报告，招募了46名青少年：25名长期受害者和21名非受害者。在功能性磁共振成像扫描期间，参与者完成了一项冒险任务。慢性同伴受害与任务期间更大的冒险行为和日常生活中更高水平的自我报告的反社会行为有关。在神经水平上，长期受害的女孩表现出更大的激活区域涉及的情感敏感性，社会认知，认知控制，显着介导的受害群体的差异，自我报告的反社会行为。
Although behavioral and experimental studies have shown links between victimization and antisocial behavior, the neural correlates explaining this link are relatively unknown. In the current study, we recruited adolescent girls from a longitudinal study that tracked youths’ reports of peer victimization experiences annually from the second through eighth grades. Based on these reports, 46 adolescents were recruited: 25 chronically victimized and 21 nonvictimized. During a functional magnetic resonance imaging scan, participants completed a risk-taking task. Chronic peer victimization was associated with greater risk-taking behavior during the task and higher levels of self-reported antisocial behavior in everyday life. At the neural level, chronically victimized girls showed greater activation in regions involved in affective sensitivity, social cognition, and cognitive control, which significantly mediated victimization group differences in self-reported antisocial behavior.
